BEARING-SUPPORT FOR ENGINES.

SPECIFICATION forming part of Letters Patent No. 712,895, dated November 4, 1902.

Application filed December 19, 1901. Serial No. 86,539. (No model.)

To all whom it may concern:

Be it known'that I, CHARLES L. BARKEE, a citizen of the United States, residing at'Nor- Walk, county of Fairfield, State of Connecticut, have invented a new and useful Bearing- Support for Engines, of which the following is a specification.

My invention relates to the construction of engines of various types-for example, gasolene eXplosive-engines-and has for its object to provide a base or bearing-support so constructed as to insure under all circumstances and conditions perfectoiling of the shaft, the connecting-rod, and, if desired, of the piston itself without the use of oil-cups or any outside oiling devices whatever, thereby doing away with one of the most serious objections to engines of the character used in launches, motor-carriages, dac., that enginebuilders and their users now have to contend with. I have devised the novel engine-hase or bearing-support, which I will now-describe, referring to the accompanying drawings, forming part of this specification, and using reference characters to designate the several parts.

Figure 1 is a vertical section of the crankchamber of an engine embodying my novel improvement; Fig. 2, a section on the line 2 2 in Fig. l; and Fig. 3 is a plan view of thel base with the body and shaft removed.

10 denotes the base as a whole; 11, the body; 12, the shaft; 13, bearing-sleeves therefor; 14, the crank; 15, the crank-chamber, and 16 the connecting-rod. These parts mayall be of any ordinary or preferred construction.

The. essential feature of my invention is that I provide the base or `the bearing-support, however constructed, with one or more reservoirs 17 for oil or other lubricant separate from but contiguous to the crank-chamber andfeed the oil'fromsaid reservoirs to the crank-shaft by means of rings or wicks, if preferred. As I preferablyruse metallic rings 18 for this purpose,'1 have illustrated rings only in the drawings. The special shape In order to secure the desired result,

of these oil-reservoirs is of course of no importance so far as the principle of my invention is concerned. The rings are hung upon the shafts, as clearly shown, and depend into vthe reservoirs, suitable means (not shown in the drawings) being provided for filling the reservoirs. It should be understood, furthermore, that the 'use or omission of bearingsleeves, as shown in the drawings, is not of the essence of my invention. Where bearing-sleeves are used, they are cut away at the top, as at 19, to receivethe rings, so that the tops of the rings will lie in contact with the shaft and be free to be rotated by the shaft. In use oil is taken up by the rings and after lubricating the shaft passes freely into the crank-chamber,lubricatin g both ends of the connecting-rod, and in engines of the explosive type lubricating the piston (not shown) as well without any outside oil-cups or lubricators whatever. I have built en ginesnpon this plan and having tried them 'for the entire season,'-in several instances by many hours of .continuous use, have found that my novel construction meets the requirements perfectly and accomplishes results without the slightestattention to the matter of oiling that have heretofore been impossible with the greatest care and closest attena tlOU;

AHaving thus described my invention, I claim-V 'The lcombination with the crank-shaft of an engine, of a base or bearing-support hava ing a shaft-bearing and a crank-chamber and an oil-reservoir separate from but contiguous to the crank-chamber and below the shaftbearing, the walls of said reservoir being in one piece with the walls of the crank-chamber, and a ring loosely hungupon'the'shaft and depending in theoil-reservoir.

In testimony whereof I aliix my signature in presence of two witnesses.
